Given numbers are 979,539,605,903
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 979,539,605,903 is 340354245.
Find LCM of 979,539,605,903 with Prime Factorization
| 7 | 979, 539, 605, 903 |
| 11 | 979, 77, 605, 129 |
| 89, 7, 55, 129 |
Multiply the prime numbers at the bottom and the left side.
7 x 11 x 89 x 7 x 55 x 129 = 340354245
Therefore, the lowest common multiple of 979,539,605,903 is 340354245.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
979 x 539 x 605 x 903 = 288280045515
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
979 : 1, 11, 89, 979
539 : 1, 7, 11, 49, 77, 539
605 : 1, 5, 11, 55, 121, 605
903 : 1, 3, 7, 21, 43, 129, 301, 903
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 979,539,605,903, is 1.
Now, the common factors can be found like this.
979:11x 89
539:7x 7x 11
605:5x 11x 11
903:3x 7x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 11x 11 = 847
Therefore, the value for common factors is 847.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 288280045515/(1x847)
LCM = 288280045515/847
LCM = 340354245
Thus, we can understand that the LCM of 979,539,605,903 is 340354245.
